Objective To conduct a scoping review on study design, research implementation, and key findings of discrete choice experiments (DCEs) used to elicit hospice care preferences in terminally ill patients and family caregivers. Methods Following a modified scoping review methodological framework, a systematic search was conducted in both domestic and international databases from the databases inception to November 2024. Two researchers independently performed literature screening and data extraction. Results A total of 18 studies were included, of which 13 focused on cancer patients and 7 involved caregiver populations. Twelve attribute dimensions were identified, with economic dimensions, patient clinical outcomes, and service accessibility being the most frequently included. Patients placed the highest value on pain management, quality of life, and economic cost, while place of care, service quality, and service accessibility also influenced preferences. Conclusion The design and reporting transparency of DCEs studies need further improvement. Future explorations are encouraged to focus on diverse populations, attribute dimensions, and influencing factors,to provide high-quality evidence on preferences for enhancing and expanding hospice care services.
